Our house in the Nimman area has a leak, and we don't know where. What we do know is that water pressure is low now, and we often need to turn on the pump to take a shower. If you know a good plumber, we are open to suggestions. Thanks, in advance.

Having to use pump would indicate low incoming water pressure - not a leak in house - and likely due to countries current water situation. Have you checked with neighbors if they are having issues?

Or is the water pressure still lower than normal with the pump being used?

Does the pump pull from a tank or suck the muni water line?
